Craft a detailed technical illustration of a futuristic spacecraft featuring a cutaway design to expose its internal structure. The spacecraft should have a sleek, streamlined exterior in vibrant orange and metallic tones. Include annotated engineering blueprints, thorough schematics, and callouts, all set against a technical background offering an all-encompassing view of the design. Aim for a sketch-like style that combines artistic intricacy with mechanical precision, incorporating various angles and detailed exploded views of the spacecraft's components. Introduce slight creative modifications while maintaining the original concept's essence.
